Kindle Documents Relocated To Amazon Cloud Drive

Amazon streamlines its ecosystem while continuing the assault on Dropbox:

Starting today, all personal documents that you have archived in your Kindle Library will be available to access, delete, organize, and share from your Amazon Cloud Drive. You can see these documents in a new “My Send-to-Kindle Docs” folder alongside all of your saved content such as photos and personal videos. Also starting today, new documents that you save to the cloud with Send to Kindle will be stored in their native format (e.g. MS Word, TXT) so you can access them anywhere from Amazon Cloud Drive.

Yah, I have 5+5 in my account as well – like you, I assume it’s related to my Kindle hardware. But is it grandfathered or will all new Kindle owners receive this. I activated a loaner Samsung S4 a month or three back and got a bonus 48GB at Dropbox. When I got my Chromebook, I got like an extra 50GB in Google Drive too. So I got more storage than I know what to do with (although those promos have only a 2 or 3 year lifespan).
